What you see before you is a 50-milliwatt green laser on a lemon shark. It was rather bravely put there by marine biologist Luke Tipple off the coast of the Bahamas, explains Wired.

It was fastened to the shark's dorsal fin using a non-invasive clamp, so no sharks were harmed in the making of this photo. According to Tipple, the lemon shark was chosen for its "predictable and relatively docile swimming behavior during the day, ease of access in shallow water, and size of the dorsal fin." That meant they were able to keep track of the fish, and even remove the laser at the end of the day.

But is it really worthy of being an exotic toy of a super villain? Sadly not. Tipple explains:

"The laser we were using wasn't strong enough to cause ocular or thermal damage to other sea life."

Pff, some use then, eh? In fact, many detractors have claimed that the whole thing was a bit of a frivilous waste of time—which is kind of hard to argue against. But still: lasers! On sharks! [Wired]
